T o HIL whom it muy concern:

Be it known that I, JOSEPH MARGRETH,

manufacturer, a citizen of Switzerland, re-

siding at Bergedorf, nea-r Hamburg, Germany, have invented certain new and useful Improvements in Portable Acetylene-Generators; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ot 1ers skilled in the art to which it appertains to make and use the same. M'

)Iy present invention relates to a portable acetylene-generator which has very small dimensions in proportion to its capacity, andit is possible, in common with these advantages, to use unprepared carbid without an overflow of gas taking place. This is obtained by the arrangement of a vertical reticulated fitting of pyramidal or conical shape in a carbidreceptacle supported close to the casing of the water-reservoir. round which fitting the carbid is placed. The width of the base of the inserted .fitting as well as its heightagree with the corres onding measurements of the carl'Jid-receptac e. The water can flow unimpeded in a full current to the carbid. for the purpose of the sieve is not to render the passage of the water ditlicult. Accordingly it is also not made too small-meshed'l Neverthelessthe water has here little opportunity of action in consequence of the peculiar position in whichthe carbid is placed. .\loreover, an overflow of gas avoided, for the reason that the space forthe gas increases toa corres )onding extent as the layers of carbid wlnch become transformed into gas become wider.

The accompanving drawing is a vertical section through the generator.

The in which a bell b is arranged so that it can be removed. The bell b is open below and provided above with an outlet-tap d.

like clamping-spring pushed in between these or, as shown 1n the figure, bv fastening-a 'cross-bar e to the pipe c, which bar engages E under the flange of the reservoir a. The flangesahowever, cut away at one place, so

cross-bar e is over the opening.

to the height of the bell in such a way that the bell is only about half the height of the reservoir. The latter is the height of the re- The bell f l; 1s fastened 1n the reservoir (l by a wedge- ,quired gas-pressure-thus about eighty to one hundred,centi-meters.

The carbid-receptacle f is in the bell b, said receptacle f consisting of a receptacle coveredv over above, but open below at g. The upper lid is provided with openings for i the emission of gas, so that the gas enerated in the receptacle can escape throng i the pipe c. The base of the carbid-receptacle stands somewhat above the base of the reservoirva, which can be arranged by means of feet h or the like.

The rece taclef may be held in the bell b by optional) fastening devices which are not shown on account of clearness.

i A cone or a pyramid t', of wire-gauze or perforated sheet metal, is placed in the receptacle f in such a way that only the space outside said pyramid can be filled with carbid. It is clear that with this arrangement only quite small annular surfaces are in the first place attacked by the water in the lower part of the carbid-receptacle, and only later, when f the lower layers are used up, the surface of i the carbid in contact with the water becolnes gradually greater.

an exceedingly constant generation of acetyr lene gas thus takes place. In order to prevent the upper )ieces of carbid being able to g fall down into t ie mud underneath when the E lower la'yers are used u transverse pieces of l metal k are put over t 1e pyramid, which in this case carry the carbid.

The burner has a simple sleeve m, which is able to be screwed onto the gas-pipe, said sleeve being preferablv provided with a slit I m. The purpose of the latter is to conduct l. sleeve.

Having thus described my invention, what I claimasnew, and desire to secure by Letters Patent of the United States, is

nation of ya water-reservoir, a gas-bell su.

ported therein, and a carbid-receptacle withinl said gas-bell, said carbid-receptacle being walls and openings at the bottom and top for the inflowof water and exit of gas, said receptacle being provided with sup ortinU-legs, and a erforated conical fitting ocated withl in sai( receptacle and running from the ceni ter of the top thereof approximately'to the t circumference of the bottom thereof, substantially as described.

It has been found that away water of condensation collecting in the l. In an acetylene-generator, the combicomposed of a vessel having imperforate 2. In an acetylenegenerator, the combination of a'water-reservoir a gas-bell located therein, and a carbid-receptacle within said as-bell,.'said receptacle being about half the 5 ei ht of said water-reservoir, and said receptac e comprising lmperforate Walls, sup orting-le s, a Perforated bot-tom and top, iori- Zonta partitions, and ay perforated conical itting within said receptacle arranged with Io its basedirected downward and running from the center of the top of the receptacle approximately to the circumference of the bottom of the receptacle, substantialhv as described.

In tescimon)v whereof I have aiixed my signature in presence of two witnesses. JOSEPH MARGRETH.
